Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105680, here are decompositions:

7 + 105673 = 105680
13 + 105667 = 105680
31 + 105649 = 105680
61 + 105619 = 105680
67 + 105613 = 105680
73 + 105607 = 105680
79 + 105601 = 105680
139 + 105541 = 105680

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.680 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
